The NSI834x devices are high reliability quad-channel digital isolators. The NSI834x device is safety certified by UL1577 support 5kVrms insulation withstand voltage, while providing high electromagnetic immunity and low emissions at low power consumption. The data rate of the NSI834x is up to 100Mbps, and the common-mode transient immunity (CMTI) is up to 200kV/μs. The NSI834x device provides digital channel direction configuration and the default output level configuration when the input power is lost. Wide supply voltage of the NSI834x device supports to connect with most digital interface directly, easy to do the level shift. High system level EMC performance enhance reliability and stability of use. AEC-Q100 (Grade 1) option is provided for all devices.
